Using a second cohort of Australian school students, this study repeated the propensity score analysis reported by Dempsey, Valentine, and Colyvas (2016) that found that 2 years after receiving special education support, a group of infant grade students performed significantly less well in academic and social skills in comparison to matched groups…

We use administrative data to measure whether attending a charter school in Denver, Colorado, reduces the likelihood that students are newly classified as having a disability in primary grades. We employ an observational approach that takes advantage of Denver's Common Enrollment System, which allows us to observe each school that the student…

African American and Hispanic students receive more punitive school discipline than White students even when students of color commit similar infractions as Whites. Similarly, students with a disability status are more likely to experience harsher discipline in schools compared to their counterparts without a disability label. This study examines…

Latent transition analysis (LTA) was initially developed to provide a means of measuring change in dynamic latent variables. In this article, we illustrate the use of a cognitive diagnostic model, the DINA model, as the measurement model in a LTA, thereby demonstrating a means of analyzing change in cognitive skills over time. An example is…

Oral reading fluency (ORF) has been widely used as a measure of students' overall reading competency. However, accuracy, or words correct per minute (wcpm), derived from ORF testing may not reveal all aspects of a student's reading abilities. The present study investigated the oral reading miscue patterns of students with and without learning…

Aim: The aim of this study was to identify subgroups of children born moderately preterm (MPT) and term with distinctive levels and patterns of functioning, and the perinatal and demographic factors that predict subgroup membership. Method: A total of 378 children aged 7 years, 248 MPT (138 males, 110 females; gestational age 32-36 wks) and a…

This study investigated the prevalence and stability of latent classes at risk for reading disabilities (RD) in elementary-aged children whose first language is Spanish. To this end, children (N = 489) in Grades 1, 2, and 3 at Wave 1 were administered a battery of reading, vocabulary, and cognitive measures (short-term memory [STM], working memory…

This study considered the efficacy of a differentiated approach to vocabulary instruction for learners with word-finding difficulties (WFD) in the speech and language pathologist's room. Using a pretest-posttest design to study treatment outcomes, 10 second graders with WFD received first semantic-based vocabulary instruction (S) and then…

This study extends recent findings of a relationship between the relative age of students among their peers and their probability of disability classification. Using three nationally representative surveys spanning 1988-2004 and grades K-10, we find that an additional month of relative age decreases the likelihood of receiving special education…

We present evidence that the positive relationship between kindergarten entrance age and school achievement primarily reflects skill accumulation prior to kindergarten, rather than a heightened ability to learn in school among older children. The association between achievement test scores and entrance age appears during the first months of…

An observational study of reading instruction was conducted in general education, resource, and self-contained classrooms, grades 1-4, in public schools. Participants included students who were deaf or hard of hearing and their reading teachers. Results indicated that time engaged in reading and/or academically responding varied significantly by…
